On a conceptual hierarchy of time,space, and other dimensions

Several observations about the way humans conceive of attributes, changes and covariation of stimuli are presented as indications for the existence of a conceptual hierarchy of dimensions in which time dominates space, and space dominates every other dimension.     

Leisure patterns among retired workers: Spillover or compensatory trends?

Leisure behavior patterns after retirement were compared retrospectively with those of the preretirement period. The data, which related to former industrial and service workers in Israel, were examined within the context of the spillover and compensatory hypotheses, with retirement representing a non work sphere. Findings revealed a spillover effect, characterized by a high degree of passive, solitary leisure behavior both before and after retirement.     

Consistency in interpretation of probabilistic phrases

It is occasionally claimed in both applied decision analysis and in basic research that people can better use and understand probabilistic opinions expressed by nonnumerical phrases, such as “unlikely” or “probably,” than by numbers. It is important for practical and theoretical reasons to evaluate this claim. The available literature indicates that there is large variability in the mapping of phrases to numbers, but provides no indication as to its cause. This study asks (a) whether the variability can be attributed to how people interpret the phrases per se, rather than to how they use the number scale and (b) whether the variability is due primarily to between-subject or to within-subject factors. In order to answer these questions, 32 subjects ranked and compared 19 probability phrases on each of three occasions. The results show that individuals have a relatively stable rank ordering of the phrases over time, but that different individuals have different rank orderings. Practical and methodological implications of these data are discussed.     

Critical levels and magnitude of effects

Researchers sometimes report an effect of an experimental manipulation on a dependent variable in terms of the difference between levels of a certain nuisance variable required in the different experimental conditions to reach a given criterion of behavior. This method, however, may yield illusory impressions about magnitude of effects.     

Asymmetry of cognitive functioning as a possible predictor for vocational counseling and personnel classification

Neuropsychological research indicates the asymmetrical functioning of the cerebral hemispheres. The right hemisphere appears to specialize in global, synthetic, spatial, time-independent processing, whereas the left hemisphere is dominant in analytic, verbal, sequential, time-dependent processing. It is proposed here that in tasks, jobs, and occupations entailing hemisphere-specific abilities, personnel with superior functioning of the relevant hemisphere would perform more proficiently. A test battery designed to assess hemispheric dominance was administered to two groups, Economics and Arts students. Significant differences in mean performance were found between groups, as predicted. The findings suggest that the identification of individual patterns of hemispheric specialization may be useful for matching people's abilities with job demands.     

Rhythm length and hemispheric asymmetry

Conflicting evidence has appeared in the literature concerning hemispheric asymmetry in the perception of rhythm. The present study investigated the effects of rhythm length on relative cerebral dominance. Twenty-four subjects were presented with sequences of one to four time intervals bounded by light flashes. The subjects' task was to determine if two such sequences were the same or different. The first rhythm was presented in both visual fields and the second only to one visual field. Reaction times and number of errors were recorded. It was found that increasing rhythm length resulted in a shift in cerebral dominance from left to right hemisphere. An interpretation of these findings was suggested in terms of the preferred mode of processing of each hemisphere, analytic vs. holistic.     

Effects of early hospital-based intervention on mothers and their preterm infants

Mothers of eight Israeli preterm infants were exposed to a standardized but individualized intervention during their stay in the hospital and before their infants were discharged. Mothers and infants in the intervention group were compared to eight control subjects using various outcome measures. While the intervention did not affect maternal personal attitudes and feelings, it positively affected the mother-infant interactions and mothers' perceptions of their infants. The importance of individualized interventions with parents of preterm infants is discussed.     

Forest before trees: The precedence of global features in visual perception

The idea that global structuring of a visual scene precedes analysis of local features is suggested, discussed, and tested. In the first two experiments subjects were asked to respond to an auditorily presented name of a letter while looking at a visual stimulus that consisted of a large character (the global level) made out of small characters (the local level). The subjects' auditory discrimination responses were subject to interference only by the global level and not by the local one. In Experiment 3 subjects were presented with large characters made out of small ones, and they had to recognize either just the large characters or just the small ones. Whereas the identity of the small characters had no effect on recognition of the large ones, global cues which conflicted with the local ones did inhibit the responses to the local level. In Experiment 4 subjects were asked to judge whether pairs of simple patterns of geometrical forms which were presented for a brief duration were the same or different. The patterns within a pair could differ either at the global or at the local level. It was found that global differences were detected more often than local differences.     

Aspects of fear of personal death,levels of awareness,and religious commitment

This study used a multidimensional and multilevel approach to study the relation between fear of death and religious commitment. A multidimensional self-report measure of fear of personal death, four TAT cards known to elicit a relatively high frequency of death themes, and an index of Jewish religious commitment were administered to 178 young male Jewish Israelis. Unidimensional and multidimensional analysis of these measures suggested that Jewish religious commitment is related to a heightened specific sensitivity to death at different levels of awareness.     

Personality types and motivational characteristics of academics versus professionals in industry in the same occupational discipline

The present study suggests that individuals belonging to different job categories—academics versus professionals in industry—differ in personality types and in motivational characteristics even though they are of the same occupational discipline. Subjects were 49 academics and 45 professionals in industry of two disciplines: engineering and management sciences. Holland's 6 personality types and 18 motivational characteristics measured in terms of Vroom's expectancy theory of motivation were used as the discriminant variables. Results indicate that academics are discriminated from professionals in industry by scoring significantly higher on the Artistic type and significantly lower on the Enterprising type even when the discipline is controlled. The distinction between the two groups is much deeper when motivational factors are examined: Academics are motivated by the opportunity for scientific contribution, for autonomy, and for the high status attained in their job. By contrast, professionals in industry are highly motivated by the opportunity for exercising power.     

Developmental aspects of visual hemifield differences in perception of verbal material

The effect of acquisition of reading on visual field asymmetries for verbal material was investigated in school-age children. Contrary to the expectation that acquisition of differential scanning tendencies will operate on perceptual asymmetries, it was found that right visual field superiority which was independent of scanning direction appeared at the fifth grade. This, and the presence of slight left field superiority at the age when reading is initially acquired, suggests that hemispheric dominance and its attributes, parallel and sequential pattern recognition processes, is the major factor which determines the field preference for verbal material.     

Immigrants preparing for their second career: The behavioral strategies adopted

On the basis of the assumption that career change for immigrants is not generally anticipated and is characterized by status incongruence, this research tested the action of the dissonance model on 89 immigrants who were obliged to prepare for a new occupation. Four coping strategies were found combining high vs low level of self-image and vocational involvement with positive vs negative attitudes toward work and authority figures at the places of work. The comparative efficiency of these strategies was tested—both with regard to an objective vocational criterion and to satisfaction and optimism regarding the future.     

How is performance limited: Testing the notion of central capacity

Two-dimensional pursuit tracking task was employed in three experiments designed to test three predictions of the central capacity model of performance limitations under time-sharing conditions. These are the predicted effects of change in task difficulty, task emphasis and their interaction. Each of simultaneously performed tracking dimensions (horizontal and vertical) was treated as a separate task and manipulated independently. Tracking difficulty on each dimension and their relative emphasis were jointly manipulated. When frequency or velocity of target movement served as difficulty parameters, and control complexity was relatively low, tradeoffs between dimensions in different priority conditions were small and task difficulty had no effect on the performance of the concurrent task, neither did it interact with task emphasis. When control complexity was increased and in addition was manipulated as the difficulty parameter, linear tradeoff was observed and difficulty seemed to interact with task emphasis. These results cannot be easily accommodated within a strict central capacity model. An alternative interpretation based on a multiple capacity approach is outlined.     

Bilingualism and brain functional asymmetry

The task of the neural organization of the native language, acquired by a direct method and of another language, studied at school, performed correspondingly by the left and the right hemispheres, was studied in the bilingual patient after unilateral electroconvulsive therapy used in psychiatry. It was established that in such a bilingual type the right hemisphere is concerned with the formation of deep semantic structures of the native language while the left hemisphere is responsible for the formation of second language deep structures and of surface structures of both languages. The effect of language learning method on cerebral organization of bilingualism is postulated.

On the basis of early transitivity judgments

This research had two aims. The first was to test three explanations of performance on N-term series tasks by young children: the labeling model of B.DeBoysson-Bardies and K. O'Regan (1973), Nature (London), 246, 531–534, the sequential-contiguity model of L. Breslow (1981, Psychological Bulletin, 89, 325–351), and the ordered array or image model of C. A. Riley and T. Trabasso (1974, Journal of Experimental Child Psychology, 17, 187–202). In the first experiment, 5-year-old children were taught additional premises which would interfere with labeling and sequential-contiguity processes, but not with forming an ordered array. Reasoning performance was essentially comparable to previous results with the paradigm, thus supporting the ordered array model. The second aim was to reexamine children's ability to learn sets of premises which can be assembled into an ordered array, since there was reason to believe that previous studies had created false positives. In the second experiment, 3- to 7-year-old children were taught either overlapping (a > b, b > c, …) or nonoverlapping (a > b, c > d, …) premises. Overlapping premises can be integrated into an ordered array (a, b, c, d, e), but nonoverlapping premises cannot. However, the overlapping condition proved more difficult, and the success rate for preschoolers ($\text{3}\text{1}\text{2}\text{-}\text{to 4}\text{1}\text{2}\text{-year-olds}$) was of zero order. This raises doubts about their ability to learn a set of premises of the kind required for transitive inference. These doubts were strengthened by the third experiment which showed that when premises were not presented in serial order, preschool ($\text{3}\text{1}\text{2}\text{-}\text{to 4}\text{1}\text{2}\text{-year-old}$) children could not learn the premises of an N-term series task.     

Electroencephalographic and dichotic indices of cerebral laterality in stutterers

To test the hypothesis that stuttering is the product of faulty cerebral laterality four experiments were performed on each of five adult stutterers and five fluent speakers. These tests were: (1) dichotic listening with consonant-vowel pairs, (2) alpha recording over both hemispheres during the performance of cognitive tasks intended to engage preferentially the left or right hemispheres, (3) contingent negative variation with either an articulatory or bilaterally symmetrical response, and (4) readiness potential with the same responses. The results fail to disconfirm the null hypothesis regarding stutterers and their fluent peers. All subjects showed consistent patterns of cerebral laterality indicative of localization of speech function in the left hemisphere. Suggestions are made regarding a possible contribution of deficient sensorimotor integration in stuttering.     

The understanding of young children and adults of the deictic adequacy of communications

When a communication is used in a discourse context, the deictic information in the communication may be important in achieving a successful speech act. This information includes the temporal and spatial coordinates of the speech act that locate the communication in a context. In the present study, first- and fourth-grade children (6 and 9 years of age) and college adults were read short stories and asked to evaluate the adequacy of deictically ambiguous or informative communications (Experiment 1) or situations (Experiment 2). The results showed that subjects in all the grades discriminated among the deictically adequate and inadequate communications and situations, though the first graders made fewer correct judgments than did the other subjects of the adequacy of the informative communications and situations.     

Organization of short-term verbal memory in language areas of human cortex: Evidence from electrical stimulation

Short-term verbal memory (STVM) performance was measured during electrical stimulation of human left frontal-parietal-temporal cortex, at craniotomy under local anesthesia for the treatment of medically intractable epilepsy. The areas of cortex where stimulation alters language, as measured by object naming, are separate but adjacent to the areas where stimulation alters STVM. There are differential effects of stimulation during input, storage, and output phases of STVM at different cortical sites. These suggest that cortex adjacent to the posterior language area is a site of storage of STVM, while cortex adjacent to anterior language area is involved in retrieval from STVM.
